HELLO I´M USING TRK-KEA128 BOARD, I'M TRYING TO READ A CAN MESSAGE BUT CAN´T SEE ANY RESULT. I DON´T KNOW IF IT IS READING OR NOT, I DON´T KNOW WHERE CAN I SEE DE DATA. I'M USING CW AND THE CODE I'M USING I DOWNLOAD IT FROM KEA Reliable, Low-power MCUs|NXP .THE CODE I´M USING IS:
Clk_Init();
MSCAN_ModuleEn();
GPIOB_PDDR |= (1<<16); /*! MC33901 STB, Mapped from GPIOB16 */
GPIOB_PCOR = (1<<16);
/*write your own code here*/
int err_status; //To store the return value of the driver APIs.
uint8 data[9];
int buffer_status[9];
/* Configure message buffer 0 */
Config_CAN_MB(0, 0, RXDF, 0);
/* Wait until new data has been received in message buffer 0 */
while (buffer_status[0] != NEWDATA) //Wait for the Receive ISR to finish and change the buffer status, NEWDATA indicates that the buffer has receive a new data
{ //check buffer status
err_status = Check_CAN_MB_Status(0, 0, buffer_status);
}
err_status = Read_CAN_MB_Data(0, 0, data); //Copy the received data in msCAN channel 0 buffer 0 to data;
return 0;
}
I CAN TRANSMIT A MESSAGE BUT I DON'T KNOW IF IT'S READING.
CAN SOMEBODY HELP ME??
